i v Application filed November6,1882. (NomodeL) t i To all whom it mayconcern: i

Be it known that I, CONRAD KAHLER, residing at Chicago, in the. county'of Cook and j Stateof Illinois,iand' a citizen of the United States,have inventedhanew and. useful Im proveinent in Printing-Press Folders,of which i ,the following'is a full description, reference beinghadtotheaccompanying drawings, in

The invention consists essentially in thecombina'tion, with upper andlower traveling tapes, t of a divider arranged to direct the front edge-3 5 of an advancing sheet past or by therearedge of a sheet which hasipreviouslyientered between the tapes and been stoppedin its movement,whereby two or more: sheets can be ent mnlatedldirectly uponeach otherto befolded together or for other purposes. Theinvention' embraces otherfeatures, which will'be fully hereinafter described, and set forth inthe i claim's. t p i i a In the drawings, Aindicates the fram e-work;

The frame A may be madein the form shown or of such other form anddimensions as will be suitable to adapt it to the press and room inwhich the folder is to be placed for operation. a a

The rollers B O, as beforeistated, will beilongto'theprinting-press whenthe press and folder are not supported in the same frame.

When the press and folder are built together,

then they will be connected as shown, other the rollers B (l in theposition shown. It will be understood that the folder here shown isdesigned to he used i'nconnection with a per= fecting web-printingpress, or a'press printing upon paper carried in by the press from Wisesecondary posts for supporting thetapei as to bring'these tworollersinreference to ICC \ the roll without cutting or severing until it isprinted on both sides, and for this reason I have shown thebreaking-roller D, which said roller will not be required in presseswhere the ordinary folder, and'such additional rollers as will give thedesired number of folds will be placed below them. As I have. notimproved this part of the folder, I have only shown one pair offolding-rollers with their accompanying folding-blade Q. In rear of thebreakingrollers D J,and in proximity thereto, is placed the shaft aforoperating the dividers, switches,

-or guides b b b, which rod is suitably supported and journaled in theframe. It is provided with the switcher guide fingers b, whichguide-fingers are provided with heels orrrear projectionsfor holding upthe rear ends of the sheet or half-sheet of paper which is passedoverthem, which sheet is stopped by the plates j before it is passedentirely 01f from the heels of the fingers or blades 1), so that whenthe sheet or half-sheet passes under these fingers or blades it will becertain to pas'sunder thesheet which has preceded it, and is thereresting against the stop. In the modification. of these fingers shown atFigs. 8 and 9, the shaft a is placed over both sets of tapes, and thefingers or guides I) work from above and are made curved, so as to actas hooks for hooking the rear edge of the first sheet or halfsheet,which has been stopped, to insure the under passage of the followin gsheet or sheets. The rocking of the shaft will inits movementsalternately drop and pick up the rear edge of the stopped sheets, so.that by the use of this the form shown in Fig. 8, the machine is to beso timed as to lift the rear edge of the stopped sheet or sheets, sothat thead vancing, sheet will pass under the stepped sheet or sheetsand, will let the sheets down again upon the lower set of tapes. In thisform I) the shaft or is made rotary instead of being made to'rock orvibrate, and I have shown at Fig.

- 13 suitable gearing for rotating it'and timing it to lift the rearedge of the sheet or sheets at the proper time for the advancing sheetor half-sheet to pass under the stopped ones,and as in this rotary formthe fingers move in their travel in the same direction as the printedsheets they can be made to operate when the printed sheets follow eachother with only a narrow space between them, and as these fingersb donot pass into or out of any space they move along and get out of theway. The object of these several forms is to cause the advancing sheetsto pass under the stopped ones.

The stop rod or shaft i crosses the folder, andis suitably supported andjournaled in its frame-work. This rod is located below the tapes,immediately below the lower ones, and is provided with the plates orfingers j, which operate between all or a portion of the tapes, andcross the space between the two sets, as shown. This rod may be locatedabove the tapes; but I prefer the position below, as shown, for thereason that it is designed to be turned as soon as the last sheet to becumu- I lated reach-es it, the upper ones having been brought to a fullstop, and in starting have a sufficient time to resume their originalmovements, so as to take the same speed as the as shown the rod or shafti is rocked by the arm is, the connecting rod or link 1, and thecam-lever n, the upper end of which lever is provided with ananti-friction :roller. As. the

cam-wheel Mrevolves the short arm of the le-' "er a is held out, asshown, which position throws the long arm. of the lever forward andholds the stopsj in the vertical position shown for. stopping the sheetsin their path of travel.

As'the wheel M rotates the short arm of the lever 41. drops into thedepression 0 and brings the springs m into operation, which, by means ofthe arm k, rocks the shaft 1 and throws the stop down into the positionshown in Fig. 7. The spring m is operated by the pendant or support 1;,which-is attached to the frame, and the stop g, which is attached to therod. There is the same arrangement for the spring e, pendant f, and stopg on the opposite side, working in connection with the cam-wheelor diskL, for rocking the shaft a at the proper intervals of time.

The stops'g g may be provided with screwthreads, so as to increase ordiminish the tensions of the springs e m.

The action of the rod d and its springis the same as that of the rod 1,except that it may have a direct connection with the cam-wheel L by itsanti-friction wheel h, Fig.1,the spring 0 being arranged to hold therear end of the said rod against said cam-wheel L.

When the shaft or is made rotary, as shown in Figs. 12 and 13, then thegearing shown in Fig.13 is added, and the devices for rocking the shaftor shown in Fig. 1 may be omitted,

2. The combination,with the upper and lower tapes, of a divider fordirecting the front edge of an advancing sheet past or by the rearedgeof a sheet which is stopped between the tapes, substantially asdescribed.
